部署Django时，使用

0.0.0.0捆绑监听服务器上的全部网卡IP地址

此时访问遇到

报错：

Invalid HTTP_HOST header: '192.168.2.157:8080'. You may need to add '192.168.2.157' to ALLOWED_HOSTS.

Bad Request: /favicon.ico

解决方法：

　　修改settings.py

ALLOWED_HOSTS = ['192.168.2.157','127.0.0.1']

　　值为'*'，可使全部的网址都能访问Django项目了，失去了保护的做用，能够用于测试

ALLOWED_HOSTS = ['*']
